from onevehicle to another vehicle whereby the latter may beadvised asto the contemplated action of the former./

It is an object of our invention toprovide a device of the characterindicatedthat will be simple in form, construction andoperation/andpractical and eflicient in application. A further object isto provide an attachment, for automobile look-back mirrors 7 whereby thesaid mirrors may be utilized for the purpose specified thereby securinga sati'sfactory and positive signal with a minimum of'mechanicalcomplication and without adding materially to the visible mecha nism ona machine.

"In the drawing:

Figure 1 is an elevation of the device in position, parts being brokenaway.

Fig. 2 is a sectional view on" line 22 of Fig. 1. V

Fig. 3 is a diagrammatical illustration of the Wiring system of thedevice.

Referring more particularly to the drawing, 1 indicates a portion of oneof the ver tical members of the framework of an automobile top, to whichis firmly secured an arm 3 by means of clamp 2, the arm 3 supportingmirror 4 in the well known manner.

Supported upon the upper edge of mirror 4 and extendin a distance overthe front thereof is a hood 5 secured thereto by a supporting member 6as shown. lVithin hood 5 are mounted a pair of electric light bulbs as 7and respectively operatively positioned in an electric light circuit 9.The wires forming a portion of the circuit S) are carried to bulbs 7 and8 through conduits 10 I anmomomnnsiennn.

11 and 12 formed in supporting member 6,

and conduit 13 in arm thence out through orifice 14: in arm 3 to aswitch 15 mounted 1 red and green respectively, and the buttons ofswitch 15 indicated at 17 and 18, are

colored red and green respectively to cor respond with the bulbsoperated by them If. button 17 is pressed, then bulb 7 is being shieldedfrom direct observation by hood 5, is thrown downwardly upon'mirror 4 sothat anyone who can see the mirror is warned that the vehicle is aboutto stop. I If the button 18 is pressed then a green light is thrown uponthe mirror and observers thereof are warned that'the "ehicle is about toturn in one-direction or the other. The effect in either case is todisplay a clear, luminous signal of sufficient size and carrying poweras to be readily distinguished at a distance,

and this without adding any substantial amount of equipment to theautomobile.

It is understood of course that any. number of bulbs may be used and ofany desired assortment of colors, and that any suitable type of switchmechanism may be used. It is further-understood that changes in form,

construction, operation and general arrangement of parts, members andfeatures may be made Within the scope of the appended claim.

We claim:

The combination with a look-back mirror for automobiles, of a hoodmounted upon the edge thereof and extending a distance over the frontthereof, a pair of illuminating units of different colors mounted in anelectric circuit and positioned under said hood whereby the lightemitted therefrom is concentrated on said mirror, and means forrendering either unit operative or inoperative.
